| Summary: | The fast technological development in electronics fields leads to the increasing use of non-linear loads in households, offices, industry, or other fields. Harmonic caused by non-linear loads are very unique, which means that each non-linear load produces different nature a characteristcs of the resulting harmonic. Usually, non-linier loads have so complicated equivalent circuit that it is more difficult to describe the nature and characteristic of each non-linier load. Therefore, in order to make the study easier, modeling approach of non-linier loads is needed so that it makes it easier to see the nature and characteristics of them. In this approach, harmonic current wave is used as the base to make simulation model of non-linear load using current source in SIMULINK MATLAB. By using the concept of phase shifted and phase sequences current source are connected in parallel in which each current source represent one harmonic order. From simulation, it is found out that the result is approximately the same as that of laboratory test. The harmonic current wave is the same at phase a, phase b, and phase c, with 120 º shift. |
